I'm offered Fred Jackson for Andre Johnson. Seems ok because my my RBs are Benjarvis and Tolbert. My other WR is Stevie Johnson. I would also like to get AJ Green out of this or is that asking to much?

Im in an 8 team league so all teams are pretty stacked I have Romo and Schaub I am trying to trade Schaub and mike williams (tampa) or Manningham for Stafford I also have Calvin and Vjax so can afford to lose a reciever would u rather get rid of Williams or Manningham or stay put?
